The “etiquette” is another chain which is used to constrain, control and oppress others.
I keep coming back to this quote, emphasis mine:
The question of “free press” and “free speech” is not separable from the question of the dictatorship of the bourgeoisie versus the dictatorship of the proletariat. The idea of “political plurality” as such turns out to be the negation of the possibility of achieving any kind of truth in the realm of politics, it reduces all historical and value claims to the rank of mere opinion. And of course, so long as someone’s political convictions are mere opinion, they won’t rise to defend them. And so the liberal state remains the dictatorial organ of the bourgeoisie, with roads being built or legislation being passed only as commanded by the interests of capital, completely disregarding the interests of workers. Under regimes where political plurality is falsely upheld as a supreme virtue, the very notion of asserting oneself as possessing a truth appears aggressive and “authoritarian.”
